What is 9.01x10^3 in scientific notation
Alchen [17]
9.01 * 10^3 in scientific notation is 9.01 * 10^3.

I got this answer by moving the decimal so there is a non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent of the 10. If the decimal is binge move to the right, the exponent will be negative, but if the decimal is being moved to the left the exponent will be positive.

I hope this helps! :>

You are conducting a study to see if the accuracy rate for fingerprint identification is significantly different from 0.4. You u
Ludmilka [50]

Answer:

a)

<em>Calculated Z -value = 2 < 2.326 at 0.02 level of significance</em>

<em>Null hypothesis is accepted</em>

<em>The accuracy rate for fingerprint identification is not significantly different from 0.4.  </em>

<em>b)</em>

<em>P-value of this sample = 0.0455</em>

<em></em>

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given sample size 'n' = 298

<em>Sample proportion </em>

<em>                             </em>p^{-} = \frac{x}{n} = \frac{136}{298} = 0.456<em></em>

<em>Population proportion </em>

                          p = 0.4

<u><em>Null hypothesis</em></u> :-

<em>The accuracy rate for fingerprint identification is not significantly different from 0.4</em>

<em>H₀: p=0.4</em>

<u><em>Alternative Hypothesis :-</em></u>

<em>The accuracy rate for fingerprint identification is  significantly different from 0.4</em>

<em>H₁: p≠0.4</em>

<u><em>Step(ii):</em></u>-

<em>Test statistic</em>

               Z = \frac{p^{-} -P}{\sqrt{\frac{P Q}{n} } }

             Z = \frac{0.456-0.4}{\sqrt{\frac{0.4 X 0.6}{298} } }

             Z = 2

<em>Given level of significance α=0.02</em>

<em>critical value Z = 2.326</em>

<em>Calculated Z -value = 2 < 2.326 at 0.02 level of significance</em>

<em>Null hypothesis is accepted</em>

<em>The accuracy rate for fingerprint identification is not significantly different from 0.4.  </em>

<u><em> P- value </em></u>

<em>P( Z>2) = 1- P( Z <2)</em>

<em>              = 1 - ( 0.5 - A(2)</em>

<em>             = 0.5 - 0.4772</em>

<em>            = 0.0228</em>

<em>Given two tailed test   = 2 ×P( Z >2)</em>

<em>                                       = 2 ×  0.0228</em>

<em>                                      = 0.0456</em>

<em>The p-value is 0.0456</em>
